Learning and wisdom are superfluities, the surface glitter merely, but it is the heart that is the seat of all power. It is not in the brain but in the heart that the Atman, possessed of knowledge, power, and activity, has its seat.

The head is the seat of intelligence. The heart is the seat of emotion. Both have to work in cooperation with the body.

The seat of knowledge is in the head; of wisdom, in the heart. We are sure to judge wrong, if we do not feel right.

The heart is first of all the center of our being on all the different levels of our existence, not only the corporeal and emotive, but also the intellectual and spiritual. It is what connects the individual to the supra-individual realms of being. In fact, if in modern society heart-knowledge is rejected, it is because modernism refuses to see man beyond his individual level of existence. The heart is not a center of our being; it is the supreme center, its uniqueness resulting from the metaphysical principle that for any specific realm of manifestation there must exist a principle of unity. The heart is the barzakh or isthmus between this world and the next, between the visible and invisible worlds, between the human realm and the realm of the Spirit, between the horizontal and vertical dimensions of existence. In the same way that the vertical and horizontal lines of the cross, itself the symbol not only of Christ in Christianity but also of the Universal Man (al-insan al-kamil) in Islam, meet at only one point, there can be only one heart for each human being, although this single reality partakes of gradations and levels of being. The heart, then, is our unique center, the place where the supreme axis penetrates our microcosmic existence, the place where the All-Merciful resides, and also the locus for the Breath of God. Hence the profound relation that exists between invocatory prayer carried out with the breath and the heart.

There is a wisdom of the head, and... there is a wisdom of the heart.

The fullest meaning of the intellect and its universal function is to be found in the ma‘rifah or gnosis, which lies at the heart of the Islamic revelation and which is crystallized in the esoteric dimension of Islam identified for the most part with Sufism. There are verses of the Quran and hadiths of the Prophet that allude to the heart as the seat of intelligence and knowledge. The heart is the instrument of true knowledge, as its affliction is the cause of ignorance and forgetfulness. That is why the message of the revelation addresses the heart more than the mind as the following verses of the Quran reveal: O men, now there has come to you an admonition from your Lord and a healing for what is in the breasts (namely the heart) and a guidance, and a mercy to the believers. Surah (10:57) (Arberry translation)

The heart is wiser than the intellect.

The heart of wisdom is tolerance.

Knowledge is of the intellect; wisdom and understanding are of the heart.

Within the human heart dwells a shimmering effulgence whose brilliance surpasses even that of the sun. This inner Consciousness is the same as that which creates and animates the entire universe. But we are not aware of this. Even though we have come from this Consciousness, we have changed our understanding about ourselves.

The human heart is the throne of God, the council-chamber of the devil, the dwelling of angels, the vile heath of witches' Sabbaths, the nursery of sweet children, the blood-spattered scene of nameless tragedies.

Wisdom is synergy of mind and heart.

The heart is a place of secrets...

The Heart and core of everything here is good, that whatever may be the surface waves, deep down and underlying everything, there is an infinite basis of Goodness and Love.
